Vanessa Hudgens Gets Close and Personal With Austin Butler

In between enjoying milkshakes at the Bob's Big Boy diner in Burbank, California, the 'Sucker Punch' actress is spotted stealing kisses from the 'Switched At Birth' actor.

Vanessa Hudgens seems to have been left smitten by another Disney star. The former girlfriend of Zac Efron got very cozy with Austin Butler during a night out in Burbank, California last Saturday, September 17. She was even photographed stealing a kiss from him.

Radar Online reported that 22-year-old Vanessa and 20-year-old Austin hung out with friends at Bob's Big Boy until 2:45 A.M. PST Sunday (September 18) morning. Sitting on the same side of the booth in the diner, the two enjoyed milkshakes and had their faces close to each other all the times.

Earlier on Saturday night, Vanessa and Austin attended the 30th birthday party for Ashley Tisdale's sister, Jennifer, at Hollywood hotspot Lexington Social House. An eyewitness, however, didn't see anything romantic going on between the "Journey 2: The Mysterious Island" actress and the "Switched at Birth" star at the bash.

"They were together but in a large group," the source dished on the pair's Lexington outing to PEOPLE. "They were not doing anything to show that they were really together romantically but they were definitely hanging out and having fun."
